‘They have completely ruined ChatGPT,’ one user complains. Some are even canceling their paid subscriptions to ChatGPT, claiming GPT-5 is inferior to the company’s previous models.
OpenAI’s newest model, GPT-5, is here, promising better performance. But in a twist, the rollout has sparked fierce backlash because OpenAI is also retiring its older AI models, which some users have grown to love.
On Reddit’s forum devoted to ChatGPT, some users are even canceling their paid subscriptions.
“What kind of corporation deletes a workflow of 8 models overnight, with no prior warning to their paid users?” wrote one subscriber.
Previously, ChatGPT could tap into several different AI models, including GPT‑4o, o3, o4-mini, GPT‑4.1, and GPT‑4.5. But OpenAI has since replaced them with a family of GPT-5 models designed to offer a “PhD-level intelligence » and generate fewer errors.
